FIREILACE HEACING SYSTEM;

Application filed February 28, 1928. Serial No, 257,575. v i

My invention relates to fireplace heating systems and is an improvementover my prior Patent Number. 1,638,286,' lssued August 9, 1927, forfireplaces.v The primary objects of my present invention are to providea fireplace having a vfire-wellin the bottom thereof with a hot-airchamber 'completely surroundingsame together with another hot-airChamber enclosed by a radiator-plate andin .communication with 'thefirst named Chamber Whereby the maximum amount of heat from the fire isutilized in heating the air that is drawn into the chambers and returnedto the several rooms by pipes or conduits as hereinafter set forth.Other` objects are to provide means for a direct fire draft andgravitational means for discharging the ashes from the fire.

VVith the above and other'objects in .view which will appear as thedescription proceeds, the invention consists of the novel construction,combination and arrangement hereinafter described and claimed.l Theseobjects are accomplished by devices illustrated in the accompanyingdrawings; wherein:

Figure 1 is a view partly in front elevation and partly in Verticalsection as determined by the broken line 1, l of Fig. 2;

Fig. 2 is a view in transverse vertical section taken substantially on abroken line 2, 2 of Fig. 1; o

Fig. 3 is a view in horizontal section taken on a broken line 3, 8 ofFig. 2; and

Fig. st is a view in horizontal section taken on a broken line 4, ofFig. 2.

Referring to the drawings throughout which like reference numeralsdesignate like parts, the numerals 5 and 6 `indicate respectively thefloor and Vertical wall of a room wherein the fireplace is located. Saidireplace has the usual opening 7 for thefire and a chimney tlue 8leading upwardly therefrom.

A fire-well 9 is disposed in the bottom i of the opening 7 with its opentop substantially flush with the flooring 5. Said firewell has Verticalupper side walls 10 ancl lower convergent side walls 11 with a grate 12supported at their joinder substantially midway of the depth of saidwell. Said well has a restricted bottom 18 with an ashchute 14:depending therefrom whereby the ashes from thegrate will fall and becarried off by gravity as will be readily understood.

The back wall 10 of the fire-well 9 extends upwardly and iscurredoutwardly within the opening 7 in the form of a concavc radiatorplate 15.; i From a point- 16, said radiator plate slants backwardly andupwardly,

as at 18. The lateral endsof' said radiator plate at thefifloor orhearth level extend outwardly to,for1nwings'19 whose ends are set .7.

into .the side wallsofthe opening 7 as at 20. Thus a completelyenclosedV back-chamber 21 is formed by said radiator plate, walls, andflooring for reasons more fully hereinafter described. o

A casing 22 is placed completely around the fire-well 9 in spacedrelation thereto to form a bottom-Chamber 23 extendingall around saidwell. The upper edge of said casingis secured to the underside of theflooring 5 withthe exception of its back Wall which may be secured to'the Vertical wall 6 in any desired manner. It willl be obvious thatsaid bottom-chamber is sealed of with the exception of its back spacewhich is in direct communication with'the back-chamber 21 as clearlyshown in Fig. 2 of the drawings.

The cool air is draWn into the bottomchamber 23 by means of al pipe 24which may have a plurality of other pipes conlnected therewith andleading to registers or openings in 'the several rooms of the house;VThepheat from thefire within the fire-well 9 will, of course, cause theWarm air to rise into the back-Chamber 21 where it is still subject tothe heat from the fire striking against the radiator plate 15. From theupper end portion of said back-Chamber the warm air will rise throughopenings 25 and pass through pipes 26 to registers 27 where it will bethrown outl into the difas at 17, to the rear chimney wall Where itsupper edge portion is set into the masonry ferent rooms to replace'thecool air which has been drawn therefrom, thus causing a continuouscirculation. i v

For the purpose of providing ample draft for the fire within thefire-well 9 I have in- 'i stalled draft pipes 28 which may take cool airfrom points 29 within the room, such as registers or screened openings,and conduct same directly to the fire through a plurality of smallopenings 30 in the side walls of the well 9. The radiator plate'l willprojecta certain amount of heat into the room and it Will therefore beobvious that means is ino provided for amply heating the room Whereinthe device is installed.

Thug it Will be apparent that I have provided means for utlizing amaximum amount of heat generated by the fire Within the open fireplacewhich is made to serve the economic Purpose of heating the entire homeand whereby the more expensive heating systems such as furnaces and thelike may be eliminated.

I-aving thus deseribed my invention what I claim and desire to securehy'Letters Patent of the United States'is:V

1. Aifireplace heating system comprising a Vfire-we1i,'a radiatorpiatearranged to form a hack-chambera a oasing Varranged to form ahot-tom-chamber around the fire-"Well, and said hottom-chamher being indirect co1nmunication with said back-Chamber.

2. A fireplace heatng system compr'sing a fire-Well, an upstandingradiator plate for said Well arranged to form a back-Chamber With thefireplace, a casing for the lsides and tom-Chamber therewith, saidbottom-chamher inidirecgt.communication with said back- Chamber, coolair conduits for the bottom- Chamber, and Warm air conduits for thehack-Chamber.

8. A fireplace heating system comprising a firewell having convergentlower side walls,'anVash-chute dsposed in the restricted bot-tom of saidWell, draft conduits for the fire-Well, a radiator plate for the wellarranged to form a back chamher with the fireplace, caeingl for thesides and hottom of the Weii` a'dapted to fo'i'in a hottomcham- :hertherewith, said hottorn Chamber in direet communication with said'back-Chamber, cool alr conduits forthe .bottomfchamher7 and Warm airconduitsl for'V the back-Cha; i-
